Track more fish in less time and with more accuracy than ever before

The feature rich HR2 High Residence Receiver is an excellent choice for tracking many fish with higher accuracy than ever before using our family of 180 kHz transmitters (V4, V5 and V9-180 kHz). The HR2 and HR telemetry system was designed specifically to allow researchers to monitor or position many tagged animals with sub-meter accuracy.

The HR2 is capable of decoding two different methods of transmitting IDs to satisfy different study design objectives. To remain backward compatible with VR2W receivers, the HR2 can detect tags transmitting our traditional PPM (pulse position modulation) and the new HR transmissions at the same time. This means that you can use the HR2 with your existing VR2W-180 receivers in collaboration with other researchers in a large scale monitoring network or you can use HR2 receivers to set up a small scale positioning experiment.

HR2s are currently being used to monitor and position migrating salmon in rivers, eels migrating to sea and non-native predator impacts on native fish.

Applications

High residence studies of hundreds of tagged animals

Frequent and precise positioning of fish (i.e. sub-meter every second depending on tag transmission rate)

Monitor migration survival

Monitor predator and prey behavior

Multi-frequency: detects two transmission systems simultaneously (PPM & HR) to support high residence and long term monitoring studies

Flexible: detects VEMCO’s family of high frequency tags (weighing 0.42g to 2.0g) making it ideal for juvenile to large fish (20g+ weight)
